The Frank L. Smith Bank, now known as the Dwight Banking Center of Peoples National Bank of Kewanee, is a bank building in Dwight, Illinois, United States that was designed by American architect Frank Lloyd Wright. Wright's earliest designs for the building date to 1904, but it was constructed in 1905 and opened in 1906. The design of the bank building deliberately rejects the classical influences common at the time, and is meant to evoke an air of simple dignity.

Dwight is a village located mainly in Livingston County, Illinois, with a small portion in Grundy County. The population was 4,032 at the 2020 census. Dwight contains an original stretch of U.S. Route 66, and from 1892 until 2016 continuously used a railroad station designed in 1891 by Henry Ives Cobb. Interstate 55 bypasses the village to the north and west.
